I'll add this since this thread is devoid of pictures, and pictures seem to help a lot of us. This is from my cab when i was building it two years ago.
I did the measurement of each bulb's amperage and then I bought a $2 extension cord that was rated to double the combined amperage of my bulbs to ensure against meltdown.
Then I simply cut off the end that you'd use to plug your device in and cut it into segments that were big enough to go from one light to the next. Each light two pieces. One for positive and one for negative.
It's not grounded. (But neither is the lamp in your living room.)
